COIN-CONTROLLED HAND-POWER TESTER.

SPECIFICATION forming part of Letters Patent No. 394,193, dated December l1, 1888.

Application filed May 8, 138G- To all wiz/0m it 71mg/ concern:

Beit known thatl, ADELARD FRANCIS MAR- TEL, of Montreal, in the county of Hochelaga and Dominion ot' Canada, have invented cer tain new and useful Improvements in Hand- Power Testers, ol' which the lollmving is a speeilieation.

My invention relates to a machine for testing the n'uiseular strength of the hand and arin; and it consists in a novel construction and operation of the same, as hereinaft er fully described and claimed.

In the drawings, Figure l is a perspective view of in v improved tester; Fig. i, a tace view; Fig. S, a detail view.

A indicates a box or framing, and B a handle rigidly secured to one ot' the outer faces thereof. The box A is further provided on one face with a glass dial, (l, and on its interior with a receptacle or drawer, D, which opens on the rear of the box.

E represents a skeleton frame secured to the sides of' the box and extending across the saine, as shown in all the gures, the frame comprising three vertical bars, u l) c, and t-wo substantially horizontal bars, (l and e.

Projecting out through the side of the box and passing loosely through the bars l) and is a rod or bar, F, which at its outer'end is fashioned into a handle, j', which is preferably i in the saine vertical plane with handle B. There the rod F passes tlu'ough the bar or support b it is preferably made cylindrical, and beyond said support l; the rod is encircled by a strong spiral spring, g, the latter being prevented from escaping from the rod E by means of a collar, 71, rigidlv secured to the rod, as shown in Figs. 2 and o. It will thus be seen that the spring g, bearing at one end against the bar or support b and at the other end against the collar 71, serves to hold the bar or rod F in the box, and in order to draw said bar or rod outwardly the torce of the spring niust be overcome.

To one side ot' the rod F, in advance of the barb b, is secured a rack-bar, nl, which en with a pinion, H, journaled in a bracket, i, formed upon the frame E. The rackbar extends beyond the pinion H, parallel with the rod F, and has its end turned upward and Serial No. 201,595. (No model.)

provided with a plate or guardj, for a purpose presently explained.

The pinion Il is rigidly secured to a shaft,

', which latter is extended outward toward the dial-plate C and provided with a tinger or pointer, I, the shat't being opposite the cenA ter of the dial. N ow, otx course, as the rod or bar F is pulled out oi the box and the spring g thereby compressed, the rack-har G, which is rigidly secured to the rod or bar, will niove 6o with the latter and turn or ,rotate the pinion ll and the pointer I. The pointer I, in thus turnin with its shaft, will move over the dial C, and thus the torce exerted will be indicated by the finger on the dial.

In order to prevent the device from being operated without compensation, I provide a catch or retaining device which is released by the deposit of a coin of a predetermined weight or value. 7o

.l indicates a beam or lever pivoted between its ends in lugs l, fiilrmed upon the frame E, and carrying at one end a small box or receptacle, m, and at its other end a pendent dog` or bar, n, as shown in Figs. l, 2, and The lever .I is further provided with a weight, o, which is adjustable upon the lever in order to balance the saine an d vary the action thereof. The dog or bar n is made in the forni of a yoke to give the necessary weight and en- 8o in a notch, p, in the sliding bar or rod F, as shown. lVhen the dog 'n is in the notch p, as shown in Figs. l and 2, it will be seen that it impossible to pull the rod F outward, as the dog rests against the upright c on one 8 5 side and against one of the upright walls of the notch p on the other side. l'Vhen, however, a coin is dropped into the box or receptaele on, the weight of the former causes the longer arin of the lever J to descend and 9o thereby raise the dog n out of the notch and -allow the rod E to be pulled outward.

By adjusting the weight o upon the lever .I the latter may be adjusted so as to tip and release the rod F when a live-cent piece is dropped into the receptacle n1, or so that it will be necessarv to insert a quarter or a half dollar piece, or any other coin, as may be desired.

As the lever J, with its receptacle or box m roc and the contained coin, descends it moves closely to the guard j, and when the lovver edge of said guard j is reached the coin rolls out through the side of the box m beloW the lower edge of the guard and into a funnelshaped tube, K, which communicates at its lower end with the drawer D, the guard preventing the escape of the coin until the lever J reaches its proper position.

To insure the proper insertion of the coin, I employ a feeding-tube, L, which is open on the exterior ot' the box A and terminates at its inner end directly over the box or receptacle m.

In order to cause the dog n, which is pivoted at its upper end to the lever J, to rise and fall in a straight line, I provide the framing E with arm or iin ger q, which may bear against one face of the dog and prevent its swinging out of line.

It is obvious that a fiat coiled spring may be substituted for the spiral spring shown, or that a system of levers and Weights may be substituted for the spring, these being the mechanical equivalents of one another.

In using the device for testing the strength of the hand, the handle B is grasped in the palm of the hand and the fingers are passed around the handle f of the rod F.

In order to limit the inward movement of the rod F, the latter is provided with a stop or collar, r, which strikes against the outer face of the box and limits the movement of the bar.

Having thus described my invention, what I claim isl. In a device for testing muscular strength, the combination, with a graduated dial and with handles to be grasped by the operator, of a catch and a coin-receiver arranged so that when a coin is placed Within the receiver it shall release the catch and permit the device to be operated and the power or strength to be indicated upon the dia-l.

2, In an apparatus for testing muscular Strength, the combination of a registering device, handles to be grasped by the hand, a locking device to prevent the actuation of the registering device, and a coin-receiver adapted and arranged to act upon and release the locking device, and thus to permit the registering device to be actuated when a proper coin is placed in the coin-receiver.
